First, let's find the scale of the smaller to the bigger triangle:
6:6+4 = 6:10 = 3:5
3/5 = x/2
6 = 5x
x = 6/5
Try this solution (based on 3 steps: equation of the line; points in this line; equation of the plane).
The expression would be (5*6)+(5*6)=x
or you could shorten it and do (10*6)=x
Answer:
A
Step-by-step explanation:
20 x 2 = 40
30 x 2 = 60
